PRIMING DEVICE.

Specification of Letters Fatent.

Patented Apr. 20, 1929.

Application filed January 31, 1918. Serial No. 214,658.

To all whom it may concern:

Be it known that I, WILLIAM Hnrnn, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented a new and useful Priming Device, of which the following is a specification.

The subject of this invention is a priming device intended for use with an internal combustion engine to supply an additional quantity of fuel to the cylinders during starting of the engines. 7

The main object of the invention is to provide a primer which may take fuel direct from the fuel tank.

Another object is to provide means for excluding dust from the primer.

Still another object is to provide a simple, durable, and efiicient primer.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it. being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

Practical embodiments of the invention are shown in the accompanying drawings, wherein Figure 1 is a side elevation with the near side removed, portions being in section;

Fi 2 is a plan view with the top plate removed;

Fig. 3 is a view in side elevation, the near side removed, and portions in section, of a modified form of the device;

Fig. 4 is a top plan view of the fuel reservoir constructed in accordance with the present invention.

Referring to the drawings by numerals of reference, and first to the preferred form shown in Figs. 1 and 2;

In carrying out the invention a fuel reser voir 1, of any suitable form, is provided and extending inwardly from one side wall of the reservoir, and near the bottom thereof, is a tubular member 2, the open inner end of which is preferably reamed out, as indicated at 3, to provide a valve seat.

The tubular member 2 is tapped radially, to receive one end of a pipe 4 which rises from the member 3 and has its upper end threaded into a discharge nipple 5 which extends through the side wall of the reservoir 1 in vertical alinement with the tubular member 2.

A. valve (3, formed of any suitable material, is adapted to be seated against the seat 3 and this valve is preferably mounted in the apertured end of a rod which fo ms the valve stem 7. The stem 7 extends horizontally part way across the reservoir 1 and in alinement with the member 2. A coin pression spring 8 is secured to the end of the stem 7 and contacts the opposed wall of the reservoir and normally holds the valve 6 on its seat. The valve 6 may be provided with a centrally or axially disposed pin 9 which extends forwardly of the valve and enters the bore of the tubular member :2 to guide the valve and maintain it in proper position for seating.

The inner end of the nipple 5 is likewise reamed to provide the valve seat 10, and against this seat normally rests a valve 6 constructed as just described with a stem 7 and spring 8.

Brackets 11 are secured by rivets or otherwise to the inner faces of the walls of the reservoir, from which they project inwardly. and these brackets are apertured and threaded to receive screws 12 which bind the top 13 of the reservoir firmly in place.

The top 13 is centrally apertured and through this aperture projects one end of a rock shaft 1d, the other end of which has a central longitudinal bore for the reception of a pin 15 which rises from the bottom of the reservoir 1.

The lower end of the shaft 14 is provided with an annular flange or collar 14 having a radially disposed depending finger 14:", the purpose of which will be explained. The arm 16 has a hub 16 which loosely encircles the pin 15.

A crank 17 is secured to the extending upper end of the shaft 14 and by this crank the shaft may be rocked by a slight movement to unseat the valve 6 from its seat 10 and then bring the finger 14 against the arm 16 and unseat the valve 6 from its seat 3. The shaft M. is connected to both valves 6 and 6, and its movement, through crank 17, unseats both of said valves in unison.

Apertures 18 whose purpose is to admit air may be formed in the top 13 of the reservoir and these apertures may be normally closed against the entrance of dust and the like by a segmental plate 19 which is secured the valves 6 and (3 from their seats.

to the shaft l4 and turns therewith, or in any other suitable manner.

A drain cock 20 may be threaded into the bottom of the reservoir, and an overflow cock 2linay be threaded in to the side of the reservoir.

The extending end of the nipple 5 may be threaded as at 22, to facilitate attachment of the device to the intake manifold of an internal combustion engine.

it is of course understood that it is not the purpose of applicants invention to supply an additional carburetor, but on the contrary, applicants de ice contemplates providing means for supplying an additional quantity of fuel to the manifold of the engine.

The operation of the device is as follows:

The intake manifold is tapped and the nipple 5 threaded into the tapped aperture. When the engine is to be started, the air inlet openings or vents 18 are uncovered to permit entrance of air, the reservoir being supplied with gasolene, the crank is given a partial turn to rock the shaft 1% and draw Suction of the engine will draw air through the nipple 5 which will cause gasolene to be drawn through tubular member 2, and pipe to the nipple 5. From the nipple 5 the mixture of gasolene and air is drawnv through the intake manifold to the engine cylinders where it is exploded in the usual way.

After the engine is started the crank 17 is released and the shaft is rocked and the valves reseated under the action of the springs 8.

In the modification shown in Fig. 3 the structure is the same as that just describes except that the va ve closing the nipple is left out. The operation of the device is the same as when the upper valve 6 is used.

Having thus described the invention, what pipe having communication with the interior of the reservoir, and adjacent the upper end thereof, said feed pipe having a threaded portion, a tubular valve member adjacent the bottom of the reservoir and having communication with the feed pipe, a valve member, having a tapered end cooperating with the tubular valve member, for controlling the flow of fuel thereto, a spring for normally holding the valve member to its seat on the tubular valve member, a shaft extending through the reservoir and having connection with the valve member for mo"- ing the valve member in one direction.

2. In a priming device, a reservoir, a feed pipe having one of its ends positioned within the reservoir, the opposite end thereof having communication with the interior of the manifold, a tubular valve member positioned adjacent the bottom of the reservoir,

a pipe connecting the feed pipe and the tubular valve member, said tubular valve member having inclined walls, a valve stem supported in parallel relation with the bottom of the reservoir, a valve member carried by the valve stem for cooperating with the inclined walls of the tubular valve member for restricting the flow of fuel thereto, an operating shaft extending through the reservoir, an arm carried by the operating shaft and having connection with the valve stem for moving the valve stem in one direction, and means for returning the valve to its normal position.

In testimony that I claim the foregoing as my own, 1 have hereto afiixed my signature in the presence of twowitnesses.
